제품 특징

EOT's 70 W and 100 W model SLC Fiber Laser Isolators have been specifically designed for pulsed Yb fiber lasers used in marking and engraving applications. 

Marking and engraving of highly reflective metals can result in large levels of back reflection, creating the potential for non-optimal performance of the laser or even damage to the laser. This can result in unacceptable marking quality and significant down time. 

Utilizing high damage threshold optics, these isolators provide for high transmission of light in the forward direction and strong attenuation of light traveling in the reverse direction. 

Designed specifically for harsh, industrial environments, an integrated beam expanding telescope assures excellent beam-pointing stability and beam quality, which is required to assure high quality marking and engraving.

NOTE: It is recommended that the isolator be attached to the laser enclosure using a compression fitting that secures only the outer, metal reinforced jacket. The inner PTFE tube is meant as an abrasion barrier for the optical fiber and should be allowed to move freely with the fiber.
